Unless the context requires otherwise, all references to "Borden Shares" shall be deemed to refer also to the associated Rights. We are the holder of record of Borden Shares held by us for your account. A tender of such Borden Shares can be made only by us as the holder of record and pursuant to your instructions. The Letter of Transmittal is furnished to you for your information only and cannot be used by you to tender Borden Shares held by us for your account. The Merger Agreement (as defined in the Offering Circular/Prospectus) provides that Borden will redeem the Rights at a redemption price of one and two-thirds cents per Right immediately prior to consummation of the Exchange Offer. Unless and until the Rights have been redeemed, if certificates representing Rights (the "Rights Certificates") have been distributed to holders of Borden Shares, such holders are required to tender Rights Certificate(s) representing a number of Rights equal to the number of Borden Shares being tendered in order to effect a valid tender of such Borden Shares.

We request instructions as to whether you wish to have us tender on your behalf any or all of such Borden Shares held by us for your account, pursuant to the terms and subject to the conditions set forth in the Offering Circular/Prospectus. Your instructions to tender Borden Shares held by us for your account will also constitute a direction to us to tender a number of Rights held by us for your account equal to the number of Borden Shares tendered. If, in accordance with the Merger Agreement, the Rights are redeemed by the Board of Directors of Borden prior to the consummation of the Exchange Offer, tendering shareholders who are holders of record as of the applicable record date will be entitled to receive and retain the redemption price of one and two-thirds cents per Right in accordance with the Rights Agreement. Your attention is directed to the following: 1.

The Exchange Offer is also subject to other material terms and conditions, which Borden shareholders should carefully consider.
